PAPER-WINDING DEVICE.

Specification of Letters Patent.

Patented Aug. 22, 1916.

Application filed April 6, 1914. Serial No. 829,790.

To all whom it may concern:

Be it known that I, HOWARD A. DODGE, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Paper-finding Devices, of which the following is a specification.

This invention relates to paper winding devices, and more particularly to devices adapted for making a written record in a cash register, and the principal object is to provide a winding mechanism which may be Operated independently of the direct operation by the movement of the register drawer.

It is also an object to provide a winding device having advancing devices with attachments by which one or the other of said advancing devices may be disconnected, as desired.

It is a further object to provide a paper winding device having a roller and a clutch which may be moved so that the roller may be wound or rewound manually without interference with the other mechanism connected therewith.

It is a further object to provide a paper winding mechanism with an adjustable writing support which is provided with a longitudinal slot through which a knife may be readily turned to sever the paper at the desired point.

In the drawings accompanying this specification and forming therewith the application for Letters Patent: Figure 1 is a plan view of the mechanism. Fig. 2 is an end elevation of the drawer operated side, showing the apparatus mounted in a casing. Fig. 3 is a view from the manually operated side showing the cover in the casing removed. Fig. 1 is an enlarged detail section on the line H of Fig. 1, as seen in the direction indicated by the arrows, illustrating the paper-engaging latch.

More specifically in the drawings, 5 represents a shelf of a cash register upon which are mounted the side frames 6 and 7 of the paper winding device which are formed as brackets having suitable bases secured to the shelf by means of screws or other fastenings, each bracket having an extension 8 rearwardly therefrom forming bearings for a rod 9, upon which the roll of paper 10 is revolubly mounted, suitable pressure being applied to the roll by means of a flat spring 11 to preserve the tension on the roll. The

bracket 7 is provided with a rearwardly extending arm 12 which forms a bearing for the trunnion 14 of a roller 15, as well as a support for a plurality of pivoted levers mounted upon this arm.

The bracket 6 has a rearwardly extending arm 16 which is provided with a bore forming a bearing for the trunnion 17 of the roller 15. Each end of the roller 15 is provided with a toothed wheel, the one adja cent the bracket 16 being designated 18, and that secured to the opposite end intermediate the roll 15 and its trunnion 1% is designated 19. The toothed wheel 18 is adapted to be engaged by a pawl 20 preferably gravity operated, and adjustable as to its length by means of a slotted arm 21, this latter being privotally connected to a hand lever 22 pivotally mounted by a pivot pin 23 on the bracket 6. This hand lever is adapted to extend through the slot 24' in the plate 25 mounted upon the casing top 26, the ends of the slot forming a limit for the movement of the lever to regulate the amount of throw, this lever also being adapted to turn rearwardly in the direction of advancing the paper, as shown in dotted lines in Fig. 3, so that pawl 20 will not engage with the toothed wheel 18 and the roll 15 will not be advanced by this lever.

To engage the toothed wheel 19 a plurality of pawls are used, a locking pawl 28 being pivoted to the arm 12 by a pin 29, and nor mally held in engagement with the wheel by means of a spring 30. This pawl has formed on one of its sides an extension 81 which is adapted to be engaged by a pivoted lever 32 pivoted to a pin 33 on the arm 12 in such a position that when it is operated by means of the link 34 connected therewith and to the hand lever 35 provided with the finger 36 thepawl 28 will be depressed and not engage with the toothed wheel.

A gravity-operated pawl 87 is arranged to normally engage the upper periphery of the toothed wheel 19 and is connected by a pivot pin 38 to a vertically-extending lever 39, pivoted on a pin 40, carried by the frame 12 adjacent the outer end of the latter. The lever 39 extends downwardly through a slot 4-1 in the shelf 5, its lower end being placed in the path of travel of a stud 42, indicated in dotted lines in, Fig. 2, mounted on the cash register drawer; the stud 42 being adapted on opening the drawer in the direction indicated by the arrow a in Fig. 2,

to engage the lower end of the lever 39 and rock the latter to advance the pawl 37 over the teeth on the sprocket 19.

Connecting with the lower portion of the lever 39 and the bracket 7, is a spiral spring 15, arranged to oppose the movement of the lever 39 by the stud 42, and adapted to re store the lever 39 to its normal position on closing the drawer; the spring 15 operating, through the lever 39, to rotate the sprocket l9 and the paper winding roll 15 a partial revolution to wind the desired length of the paper 50 on the roller 15. The length of the stroke of the lever 39 is limited by means of a screw 47, mounted in a bracket 48, on the arm 12, and positioned to engage the lever 39 below its pivot 40. By adjusting the position of the screw 17, the length of the stroke of the lever 39, as effected by the spring 45, may be varied according to the length of movement it is desired to impart to the paper 50.

The upper end of the lever 32 is formed with an inwardly-projecting member 44, which extends beneath the pawl 37 adjacent thereto in such manner that by shifting the lever 32 to depress the pawl 28, the pawl 37 will be engaged by the projection 14: and lifted out of engagement with the ratchet 19, in which position it is maintained when the pawl 23 is disengaged from the ratchet 19. When the pawls 37 and 28 are disengaged from the ratchet 19, the latter may be freely rotated in a reverse direction to unwind the paper previously wound on the roller 15.

As a means for securing the end of the paper 50 to the roller 15, a hinged latch 51 is provided, this latch consisting of a bar.

arranged to extend longitudinally of the roller 15 and having pivoted bent ends to permit the latch bar 51 being swung in and out of a longitudinally-extending channel on the roller 15. A depression 51 is formed in the roller 15 to permit the insertion of the finger to engage the bar 51 and lift the latter out of the channel in the roller 15. Arranged between the rollers 10 and 15 is a writing plate 52, which is preferably curved transversely upon its upper surface. The plate 52 is provided with slotted depending end brackets 53 which embrace and extend on either side of the upper portion of the brackets 6 and 7 and are adjustably secured thereto by means of screws 54 engaging the slot and clamping each bracket 53 closely to the brackets 6 and 7.

A transversely disposed slot 55 .is cut in the upper face near the forward edge of the plate 52 so that the paper may be readily severed by inserting the finger nail or the blade of a knife without disturbing the other mechanism, and, as previously described, by releasing the successive pawls the amount of paper wound upon the roll 15 may be readily unwound and may be filed away as a day ledger or cash record showing the amount of each sale, and other credits or transactions as desired, together with explanations and the initials of each operator of the machine.

In the operation of the invention the roller 10, carrying the paper 50, is mounted on the rod 9, and the end of the paper is passed over the writing plate 52 and beneath the hinged bar 51, 011 the roller 15; the bar 51 being previously moved to its uppermost position, as indicated in dotted lines in Fig. 4-, to permit the insertion of the paper thereunder. The bar 51 is then moved downwardly to clamp the paper in the channel on the roller 15. When it is desired to wind the paper on the roller 15 independent of the cash register drawer, the lever 22 is manually rocked so as to advance the pawl 20 over the teeth of the ratchet 18, when the lever 22 is moved in one direction, and when moved in the opposite direction to cause the ratchet 18 to be rotated a partial revolution by the engagement of the pawl 20 therewith. On this movement of the ratchet 18, the roller 15 will revolve and wind the paper 50 thereon; the pawls 2S and 37 riding over the teeth of the ratchet wheel 19 and engaging the latter to prevent retrograde movement of the roller. By operating the lever 22, the paper 50 will be ad vanced in a step-by-step fashion on the roller 15.

On opening the cash register drawer the stud 42 will engage the lever 39 to rock the latter in opposition to the spring 45 as be fore described, to advance the pawl 37 on the ratchet 19, so that on closing the drawer tie spring 1-5 will operate to rotate the ratchet 19 a partial. revolution and thereby wind a length of paper on the roller 15 approximately corresponding to the width of the writing plate 52. The pawl 28 normally engaging the ratchet 19, will serve to prevent retrograde movement of the roller 15 during the retracted movement of either the pawl 37 or .20. By this operation each opening of the drawer will efiect a movement of the paper 50 to present a new surface on the writing plate 52. When it is desired to operate the drawer without shifting the paper 50, the hand-lever 35 is operated to rock the lever 32 to move the lower end thereof into engagement with the eX- tension 31, on the pawl 28, to crowd the latter out of engagement with the ratchet 19; the projection 44 on the lever 32 at the same time operating to elevate the pawl 37 and slidably hold it out of engagement with the ratchet 19. The lever 39 may then be rocked without efiecting a rotation of the roller 15.

When it is desired to unwind the paper 50 from the roller 15, the plate 25 or the casing top 26 is removed and the pawl 20 lifted out of engagement with the ratchet 18, while the pawls 37 and 28 are held out of engagement with the ratchet 19 by the lever 32. The paper 50 may then be severed on the slot as before described. A pull on the portion of the paper wound on the roller 15 will then operate to rotate the roller in the reverse direction and unwind the paper therefrom.
